Can parents distinguish their own children by smell alone?

To investigate, Porter and Moore (1981) gave new T-shirts to children of nine mothers. Each child wore his or her shirt to bed for three consecutive nights. During the day, the shirts were kept in individually sealed plastic bags. No scented soaps or perfumes were used during the study.

Each mother was given the shirt of her child and one shirt of another randomly chosen child. She was then asked to identify her own child’s shirt by smell. Eight of nine mothers identified their children correctly.

Answer the following questions using a two-sided test and a significance level of 0.05.

a) What is the appropriate null hypothesis?
b) What is the alternative hypothesis?
c) What test statistic would you use?
d) If Ho is true, what is the probability of exactly eight correct
identifications? (refer to the null distribution figure)
e)
If H。 is true, what is the probability of obtaining eight or more
correct identifications?
f) What is the P-Value for the test?
